Parthasarathi Chakraborty

Parthasarathi Chakraborty is an Indian environmental geochemist, a former senior scientist at the CSIR-National Institute of Oceanography and an associate professor at the Indian Institute of Technology Kharagpur, India. Chakraborty is known for his studies in the field of Environmental Chemistry. He made contributions to the field of Environmental Geochemistry, which has facilitated our understanding of metal-natural ligand interactions in natural and marine environments. He is a recipient of the National Geoscience Award-2015 and an elected fellow of the Indian Geophysical Union. The Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology, one of the highest Indian science awards, for his contributions to Earth, Atmosphere, Ocean and Planetary Sciences in 2018.

Biography Parthasarathi Chakraborty, born on 24 October 1976 in Siliguri, West Bengal India, graduated in chemistry with honors from the University of North Bengal in 1998 and continued at the institution to earn a master's degree in inorganic chemistry in 2000. Subsequently, he secured an M-Tech in industrial catalysis from Cochin University of Science and Technology in 2002 and moved to Canada for doctoral studies, earning a PhD in Chemistry (specialisation in analytical environmental chemistry) from Carleton University in 2007. He did his post-doctoral work at the Institute of Physical Chemistry and Colloid Science of Wageningen University for one year. He returned to India in 2008 to join the National Institute of Oceanography. He is a former associate member of the Working Group 139 (Organic Ligands – A Key Control on Trace Metal Biogeochemistry in the Ocean) and works as an associate member of SCOR-145 (Chemical Speciation Modelling in Seawater to Meet 21st Century Needs). He is associated with several scientific Societies and is as an associate editor of the Elsevier journal, Marine Pollution Bulletin.

Awards and honors Chakraborty was selected for the National Geoscience Award-2013 of the Ministry of Mines in 2015. He received the M. S. Krishnan Medal of the Indian Geophysical Union in 2015. Chakraborty was bestowed with the IAGC Kharaka Award (USA) in 2017. He also received ISAG Medal-2017 for his contribution in Environmental Geochemistry. The Council of Scientific and Industrial Research awarded him the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards in 2018.
